You’re Not Just Human 🦠

Your body contains more bacterial cells than human ones.
Most live in your gut — helping with digestion, disease defense, and even mood regulation.
Technically, you’re a walking bacteria hotel!

Stephan’s Quintet, a group of five galaxies, is a stunning example of galactic interaction. While four galaxies engage in a cosmic dance 290M light-years away, the leftmost, NGC 7320, is much closer. Webb reveals details of star formation, gas dynamics, and an active black hole.

The Tarantula Nebula, over 1,000 light-years wide, is the most active star-forming region in the Local Group. Located 180,000 light-years away in the Large Magellanic Cloud, its massive stars and supernova shocks shape its glowing filaments.

Comet 67P/Churyumov-Gerasimenko is a 4-km-wide, double-lobed world with a surface as dark as coal, reflecting only 4% of sunlight. Its gravity is so weak that an astronaut could jump off. As it nears the Sun, escaping gas and dust form its glowing coma and tails.

Hubble’s view of NGC 1672, a barred spiral galaxy 60M light-years away, reveals star-forming clouds, dark dust lanes, and glowing hydrogen gas. Its bar channels gas to the core, fueling new stars. As a Seyfert galaxy, its active nucleus is powered by a supermassive black hole.

A star in Pismis 24 was once thought to be 200x the Sun’s mass, making it one of the most massive ever found. Hubble later revealed it’s actually three stars, each still near 100x solar mass. Below, young stars continue to form as energetic giants illuminate the nebula.

This wide-field infrared view of the Orion Nebula (M42), 1,350 light-years away, was captured by ESO’s VISTA telescope. Its infrared vision reveals hidden young stars in dusty regions, offering a stunning glimpse into a stellar nursery.
